Hi, Phil;
I can't send pics right now.
I can tell you that after my modification, you can imagine that the clearance gap between the glass wing and the windshield frame is 1/4" top to bottom.
It used to be 1/4" gap at the top, but the wing was sitting on the frame by 1/4" at the bottom.
After my custom blocks were made; the wing can now be moved inwards to be parallel to the side of the car now, without striking the frame at the bottom because the 1/4" gap is constant top to bottom.
I did find the pic of one of the Gulf race cars and it appears to have a longer bottom mounting block and a parallel gap.
If I am correct; you should be able to look at your ERA and see a proper gap at the top of the wind wing, but this gap is not parallel to the frame all the way down.
If the lower block was 1/2" longer, and the hinge pivot point was moved by 1/2" the gap would be parallel, and the wing would operate properly.
I hope this helps everyone understand until I can get photos.
